           Code Smell

        Methods should not have identical implementations

        maintainability
        Code Smell
        • confusing
        • duplicate
        • suspicious

        Why is this an issue?

        Two methods having the same implementation are suspicious. It might be that something else was intended. Or the duplication is intentional, which becomes a maintenance burden.

        private const string CODE = "secret";
        private int callCount = 0;
        
        public string GetCode()
        {
          callCount++;
          return CODE;
        }
        
        public string GetName() // Noncompliant: duplicates GetCode
        {
          callCount++;
          return CODE;
        }
        

        If the identical logic is intentional, the code should be refactored to avoid duplication. For example, by having both methods call the same method or by having one implementation invoke the other.

        private const string CODE = "secret";
        private int callCount = 0;
        
        public string GetCode()
        {
          callCount++;
          return CODE;
        }
        
        public string GetName() // Intent is clear
        {
          return GetCode();
        }
        

        Exceptions

        Empty methods, methods with only one line of code and methods with the same name (overload) are ignored.
